CUE DATA RECORDING APPARATUS ABSTRACT OF THE DISCLOSURE Apparatus is provided for recording cue data identifying characteristics of information recorded in tracks on a magnetic tape; fox example, the cue data identifying beginning, end and various predetermined portions of program material, such as an audio program, a video program, or the like. The recorded information is played back, and a cue signal generator generates respective cue signals upon the occurrences of respective ones of the predetermined characteristics in the played back information. For example, one type of cue signal is generated when the beginning of the program is played back, another type of cue signal is generated when the end of the program is played back, and various respective cue signals axe generated when different predetermined portions of the program are played back. In addition to generating the cue signals, code signals having a predetermined relationship with the played back information also are generated. For example, the code signals may represent the relative locations on the magnetic tape at which the predetermined characteristics (e. g. beginning, end and predetermined portions) of the program are recorded. A memory stores the code and cue signals, and a format circuit produces cue data in a predetermined format as a function of the stored code and cue signals. The cue data in this predetermined format -i- then is recorded on the magnetic tape in a track which differs from the tracks in which the information is recorded. Alternatively, the cue data is recorded on a disc record, such as a master disc from which replicas subsequently may be made.
